Characteristics of microwave sterilization
In the high frequency electromagnetic field, these orientations according to the alternating electromagnetic frequency constantly changes, this process causes the movement of molecules and mutual friction to produce heat.
Conventional thermal drying sterilization is the heat transfer from the surface of the object to the inside through heat conduction, convection or radiation.
At this point the field energy of the alternating electric field can be converted into the heat energy in the medium, so that the medium temperature is rising, so the microwave heating is the dielectric material itself loss of electric field energy and heat.
Often takes a long time, inside the object to achieve the required dryness and sterilization temperature.
The medium consists of polar molecules and nonpolar molecules, under the action of electromagnetic fields, these polar molecules from the original random distribution to the polarity according to the electric field alignment orientation.
